Product Summary

The MAX483ECSA+T is a low-power transceiver for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX483ECSA+T features reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX483ECSA+T is not limited, allowing them to transmit up to 2.5Mbps. These transceivers draw between 120μA and 500μA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX483ECSA+T has a low current shutdown mode in which they consume only 0.1μA. All parts operate from a single 5V supply. Driver is short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit. The MAX483ECSA+T features quarter-unit-load receiver input impedance, allowing up to 128 MAX483ECSA+T transceivers on the bus. Full-duplex communications are obtained using the MAX483ECSA+T, while the MAX483ECSA+T is designed for half duplex applications.
